Errors in MLC NAND Flash can be classified into retention errors and program interference (PI) errors. While retention errors are dominant when the data storage time is greater than 1 day, PI errors are dominant for short data storage times. Furthermore these two types of errors have different probabilities of 0->1 or 1->0 bit flips. We utilize the(More)
In this paper, a novel accurate method for detection of copy-move forgery is proposed. The proposed method compresses digital image using Discrete Wavelet Transform (DWT) up to the certain desired level based on the image size. This reduced dimensional image is then divided into overlapping blocks of fixed size. These blocks are sorted using lexicographic(More)
This paper presents an adaptive controller with wavelet neural network tuner for a class of uncertain underactuated systems. Proposed scheme utilizes the concept of hierarchical structure error surface. Hierarchical structure is obtained by recursive coupling of error surfaces designed for individual subsystems. Error surface coupling is carried out such(More)
This paper presents an adaptive control strategy which combines the hierarchical control scheme with adaptive wavelet neural network for a class of multi-input multi-output (MIMO) underactuated systems with uncertain dynamics. Proposed scheme develops a systematic framework of the control components by applying hierarchical scheme to underactuated system.(More)
